Busch PCR-90 Vapor Absorber

Adsorption Unit for Electronic and Electrical Equipment

The Busch PCR-90 Vapor Adsorption Unit is the practical solution to the problem of creating optimum ambient conditions for sophisticated electronic and electrical equipment. The PCR-90 incorporates cooling, heating, dehumidification and many other critical environment control capabilities.

User benefits include protected circuitry, reduced airborne contaminants, extended service from instrumentation, decreased maintenance, and reduction of system failures.

Drawing on Busch Internationalís expertise in particulate and gaseous filtration, the PCR-90 provides superior efficiency in reducing the severe corrosive effects of contaminants such as sulphur and chlorine compounds. The Unit utilizes a deep bed of carbon granules which are factory-treated by a process which permits contaminant-removal capacity to be estimated with extreme accuracy. This assures cost-effective Unit size and optimization of bed depth.

An integral ìgas bypass indicator bedî monitors the full face area of the deep-bed activated carbon section. A contaminated gas stream changes the color of the monitoring bed. This provides a visual means of checking for gas bleed-through or bypass of the bed.

Busch International has many years of experience in designing ultra-high efficiency air filtration systems. This experience has been applied to the PCR-90 to extend the life of the adsorbent bed by removing clogging particulate from the entering airstream. High efficiency air filters are also used for the air exiting the Unit to protect against any particles which might be discharged from the adsorbent bed.

PCR-90ís are completely factory assembled, wired, and tested before shipment. Accessories including heating/cooling coils, economizer control systems, and humidifiers are factory installed. Wiring of starters, disconnect switches, relays and temperature controls will be installed in fully-pressurized enclosures in accordance with purchaserís specific electrical standards.

The gas reactor module is constructed of 316 stainless steel, fiberglass reinforced plastic, or aluminum - according to the purchaserís preference. The base is constructed of all welded heavy-duty structural steel members, coated to resist corrosion.
